JULY 5, 2020
A secret cave hidden underneath a Mexican pyramid offers clues about the urban design of Teotihuacan, one of the largest and most vibrant cities of ancient times.
Located about 80 kilometers outside of todays Mexico City, Teotihuacan peaked in AD 300650, well before the Aztecs. The city boasted three monumental pyramids arranged along the 2.4-kilometer Street of the Dead.
Two of the pyramids were already known to overlie caves and tunnels, which were excavated by Teotihuacanos to obtain construction materials, and were later repurposed for activities such as astronomical observations, the veneration of death and the enthronement of rulers.
Denisse Argote at the National Institute of Anthropology and History in Mexico City and her colleagues measured the electrical resistance of the ground beneath the third structure, the 43-meter-high Moon Pyramid.
They discovered a partially filled cavern about 15 meters underneath the edifice.

You kept this one out of sight, too, long enough:

(14,118 posts)Sun. When we were done viewing the area we had lunch at a marvelous restaurant located
deep in a volcanic cavern. That was a fascinating day! Thanks for the memories, Judi!

Astounding architecture.
It must have been fascinating throughout the time spent there.
Never have heard of a restaurant like the one you describe. Had to look for a photo immediately:
Oh, my gosh. What an experience.
Can anyone ever know if a volcano is completely finished with exploding? Yikes. Amazing idea.
All in one day!
Thanks for adding the information about the completely novel restaurant.

(14,118 posts)elevation in that area is about 7,000 feet. Yes, it was a great experience and thanks for the
pic of the restaurant! I never thought to look for it.
And I've read that there are dormant/inactive volcanoes but NO extinct ones.
